So far I’ve been following recommendations from this person: https://old.reddit.com/r/NewMaxx/comments/16xhbi5/ssd_guides_resources_ssd_help_post_your_questions/

Try dmraid, it’s been designed to take over various formats of hardware RAID cards.

lemmy.ml is hosted in EU, and lemmynsfw.com uses CloudFlare, which operates in EU. Worst case, issue a GDPR request to both.

Yep, it’s EU. File transfer shouldn’t be bad if your files are large, though it’s best if you tested it first—it might depend on your ISP’s peering and your prefered transfer protocols/tooling. Whether it’s reputable for your purpose, you probably have to do your own research. Also, remember that the offer I mentioned would only be equivalent in durability to a single-box RAID5 for your purposes, so not exactly equivalent to Google’s.

There’s Jottacloud with unlimited storage for 10 EUR/month, but they gradually slow down after first 5 TB. 30 TB might be a bit too much. There’s Hetzner with their dedicated 4×10TB machines for ~52 EUR, you could do RAID5 and have somewhat redundant 30 TB, at the cost of self-managing a dedicated machine. There are several providers doing regular S3 (which you can take advantage of with tools like rclone) with decent redundancy for 4-5 USD/TB + egress. For high-value data you should be probably spending more than 100 USD/month for 30TB in the cloud, or invest in actual hardware. Do you need hot access to this dataset, or is a cold storage archive enough?

Will they keep the dense email list view as an option? Seeing more than the 14 email messages visible on the screenshot in the post is useful to sort out large folders.

I’m surprised federation isn’t based on asymmetric cryptography. Let the public/private keys identify instances, as opposed to domains that risk being blocked by governments or bought by malicious third parties if the instance owner forgets to prolong it.

With that, implementing a change in domain names would be simple.
